Enum MockTimeError 

pub enum MockTimeError {
    ActiveWaiters,
    MismatchedTimeline {
        expected: u64,
        actual: u64,
    },
}

Error returned when a mock time control operation is rejected.

Mock time controls are usually infallible because tests advance time explicitly. Resetting elapsed time while a sleeper or deadline waiter is active would rewind the timeline underneath a blocked operation. Passing an instant from one timeline into another timeline would make a deadline refer to the wrong logical time source. Both cases are rejected instead of silently producing inconsistent deadline behavior.

Variants

ActiveWaiters

The operation would reset a timeline while waiters are still registered.

MismatchedTimeline

The operation received an instant created by a different timeline.

Fields

expected: u64

Timeline id expected by the operation.

actual: u64

Timeline id carried by the provided instant.

Trait Implementations

impl Clone for MockTimeError

fn clone(&self) -> MockTimeError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MockTimeError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for MockTimeError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the mock time error.

impl Error for MockTimeError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for MockTimeError

fn eq(&self, other: &MockTimeError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
